Fixed precendence bug that meant setting skip_blanks to false didn't work
under some circumstances.

Factored the guts of 'warn()' out to 'gen_error()', and added the
'error()' method (trivial thanks to the refactoring).

Dropped the 'collapse_ws' option and replaced it with 'collapse_join' --
it's *much* faster (no 're.sub()') and this is the reason I really added
'collapse_ws', ie. to remove leading whitespace from a line being joined
to the previous line.

(eg. "bdist_dumb", to generate both ZIP and tar archives in the same
run), tell all but the last run to keep temp files -- this just gets
rid of the need to pseudo-install the same files multiple times.

Run "install" the right way, by calling 'run_command()'.

real implementation in Distribution.

the command's sub-commands as well (off by default).  This is essential if
we want to be be able to run (eg.) "install" twice in one run, as happens
when generating multiple built distributions in one run.

families" -- eg. install and its brood, build and its brood, and so forth.
Specifically: added the 'sub_commands' class attribute (empty list, sub-
classes must override it) and a comment describing it, and the
'get_sub_commands()' method.

meant removing 'get_sub_commands()', and moving the 'sub_commands' class
attribute to the end and restructuring it to conform to the new regime.

with the recent change in 'get_platform()', we now have directory names
like "build/lib-1.5-linux-i586".  Idea and original patch by
Rene Liebscher.

the sometimes inappropriate warning about where we're installing data files.

  of globals from sysconfig.
Added 'prefix' and 'exec_prefix' to the list of variables that can be
  expanded in installation directories (preserving the stupid old names
  of 'sys_prefix' and 'sys_exec_prefix, though).

of globals from sysconfig.

POSIX platforms, ie. get a little more detail than 'sys.platform' gives.

all that work when someone asks for a "configuration variable" from the
Makefile.  Details:
  - added 'get_config_vars()': responsible for calling one of the
    '_init_*()' functions to figure things out for this platform,
    and to provide an interface to the resulting dictionary
  - added 'get_config_var()' as a simple interface to the dictionary
    loaded by 'get_config_vars()'
  - changed the '_init_*()' functions so they load the global dictionary
    '_config_vars', rather than spewing their findings all over
    the module namespace
  - don't delete the '_init_*()' functions when done importing
  - adjusted 'customize_compiler()' to the new regime

Takes care of the extra_path argument to the setup function,

distutils/command/bdist_wininst.py:
- the windows installer is again able to compile after installing
  the files. Note: The default has changed, the packager has to
  give --no-target-compile/--no-target-optimize to NOT compile
  on the target system. (Another note: install_lib's --compile
  --optimize options have the same semantics to switch off
  the compilation. Shouldn't the names change?)
- All references to specific python versions are gone.
- A small bug:
    raise DistutilsPlatformError ("...")
  instead of
    raise DistutilsPlatformError, ("...")
- When bdist_wininst creates an installer for one specific python
  version, this is reflected in the name:
    Distutils-0.9.2.win32-py15.exe instead of
    Distutils-0.9.2.win32.exe
- bdist_wininst, when run as script, reads the wininst.exe file
  and rewrites itself. Previously this was done by hand.

misc/install.c
- All the changes needed for compilation
- Deleted a lot of debug/dead code

  - 'mkpath()' the distribution dir in case of empty manifest
  - warn if empty manifest
  - detect, warn about, and skip non-regular files in manifest

  bug to boot: now works even if both MANIFEST and MANIFEST.in don't exist.
Don't hardcode setup.py, use 'self.distribution.script_name'.

* ensure the "dist" directory exists
* raise exception if using for modules containing compiled extensions
  on a non-win32 platform.
* don't create an .ini file anymore (it was just for debugging)

* reverse library names from bcpp_library to library_bcpp
* move some code to the right places, to put the def-files
  in the right directories again
